Mr. Seward to General Salgar

General: I have received your note of the 22d instant, requesting the surrender for trial by the tribunals of Colombia of the marine attached to the United States steamer James Adger, who is charged with killing, at Aspinwall, on the 10th of November, 1865, of one George Holmes, alleged to be a British subject.

In reply I have to state that in the absence of an extradition treaty between the United States and the United States of Colombia, the request cannot, it is conceived, be properly complied with.

I avail myself of this occasion, general, to offer to you a renewed assurance of my high consideration.

WILLIAM H. SEWARD.

Señor General Don Eustorjio Salgar, &c., &c., &c.
